Rocket Stages
To those that know a lot more than me,
I have managed to get my son intersted in the Appolo program ( I am a complete nut about it). He has asked me why the Saturn V was staged.and not just one "big bang"..or words to that effect.
I sort of know..but I cant really expalin it....can my friends on pprune please help me to explain why there are staged rockets.
Thanks in advance
